Abstract

본 발명은 음극선관의 전자총의 전극으로부터 이물질을 방출 시키는 에이징 작업방법에 관한 것이다.The present invention relates to an aging operation method for releasing foreign matter from an electrode of an electron gun of a cathode ray tube.

본 발명에 따른 에이징 작업 중 발생하는 제1전극(G1)으로부터의 이물질이 캐소우드전극으로 흡착되어 캐소우드가 손상되는 것을 방지하기 위하여 제1전극(G1)에 저전압이 인가된 후 히터에 저전압(Ef)을 인가하는 것을 소정시간 동안 정지한 후 히터전압(Ef)과 제2,3전극(G2,G3)에 동시에 전압을 인가하고 이후 제1전극(G1)과 제2,3전극(G2,G3)에 교대로 저전압(EC1)과 고전압(EC2,EC3)을 인가하여서 수행되는 것을 특징으로 한다.In order to prevent foreign matters from the first electrode G1 generated during the aging operation according to the present invention adsorbed to the cathode and damage to the cathode, a low voltage is applied to the heater after the low voltage is applied to the first electrode G1. After stopping the application of Ef for a predetermined time, the voltage is simultaneously applied to the heater voltage Ef and the second and third electrodes G2 and G3, and then the first electrode G1 and the second and third electrodes G2, The low voltage EC1 and the high voltages EC2 and EC3 are alternately applied to G3).
